A proposal by Sen. Rand Paul to allow guns in post offices is being met with skepticism by the chairman of the committee that oversees the Postal Service.

The Republican from Kentucky floated his measure Wednesday as an amendment to a postal overhaul bill being debated by the Homeland Security and Governmental Affairs Committee. The initial reaction from Chairman Thomas R. Carper, D-Del., was not positive, but it's unclear how the votes will turn out.
